Conference Bridge in Lync Server 2010

How to create a conference bridge in Lync server 2010.

<Sorry for the quick and dirty version. I just wanted to get this out there. Will clean later>

My company wanted to go out and buy several different conference bridges this week. I decided to make a couple on our Lync server.

Requirements:
- Create separate conference bridge ID's per department
- Make them available for the whole department
- Have to be accessible from the outside

We have DID's (direct inward dial) phone numbers for each of our users. I know that I can create a new user for each of these departments, but I want them to share the same DID. So in Lync server I was able to assign the same DID to each user and give them an extension. This made them unique in Lync based off their extension number. Here is how I did it:

Step 1. Choose a DID to use
Step 2. Create your users in Active Directory
Step 3. Enable the users in Lync Server
Step 4. Give the users the same phone number with unique extensions
   Example: tel:+18885551212;ext=100
Step 5. Login to your conferencing options webpage to set the PIN
Step 6. Copy the information in the conferencing options webpage for following:
   PIN
   Conference URL
   Conference ID
Step 7. Give this information out the users/departments.
